I swear bolt is afraid to run as fast as possible. He always seems to back of at the end. would liked to have seen what time he could have done then if he didn't pull back and celebrate a few metres from the line.

I knew he would win today. When u compare their 200m semis u can clearly see bolt if just easing through the last 100m whilst gatlin only let off for the last few metres.

Steve CramBBC athletics commentator"Two golds for Bolt. He's too good for Gatlin. Silver for the American. Bolt won it in the first 200 metres. Out well and there was no way Gatlin was going to close that down.

"Resurrecting a performance like that from a season he has had shows Usain Bolt is the greatest."

Sad to see Christine lose but at least she was beaten by Allyson Felix

Fantastic from Farah for the umpteenth time. He just seems to be able to make the result a certainty every time no matter how far back he is. I actually thought this time he'd met his match - the commonwealth champion was clearly giving it everything - and he just strolled past. To go from three metres behind with 130 to go to winning by two seconds is just....flabberghasting. Utterly superb.
